signers to Lew Harbin, Manchurian Application Jilly M, 1935, gerial No. 735,1]19Vg d dilatin ($11. l97=-lll3) This invention relates to typewriting machines, and its general object is to provide a line ruling device that can be attached to practically all makes of typewriters now in genered use, in an easy and expeditious manner, and for use in drawing or ruling straight, accurate, clear and distinct horizontal or vertical lines, merely by moving the carriage of the typewriter, for horizontal lines and rotating the platen for vertical lines, after slight manipulation of the parts is made, therefore it will be seen that the lines can be drawn with very little effort on the part of the operator.

A further object of the invention is to provide a line ruling device that is movable for disposal in operative or idle positions, and when in the latter position will in no way interfere with the use of the typewriter in letter writing and the like, and in fact, our device can be used alternately with the type in writing and line drawing on the same sheet or sheets without changing their position or removing the same from the machine.

Another object of the invention is to provide a line ruling device that will in no way damage the platen or other parts of the machine, even after long usage, as pounding actionis eliminated by the use 'of our device, as distinguished from the use ,of the hyphen and dash type bars now generally employed for line drawing.

A still further object of the invention is to provide a line ruling device that includes means to exert pressure on the line drawing wheels and which is adjustable in accordance with the number or thicknes of the sheets to be lined, whereby lines drawn on carbon copies will be clear and distinct.

Another object of the invention is to provide a line ruling device in the form of an attachment for a typewriting machine, that is simple in cornstructlon, inexpensive to manufacture and ex tremely eficient in operation, use and service.

v This invention also consists in certain other features of construction and in the combination and arrangement or the several parts, to be hereinaiter fully described, illustrated in the accord-- panying drawing and spmificaily pointed out in the appended claims.

In describing our invention in detail, reference will be hade to the accompanying drawing where= in like characters denote like or corresponding parts throughout the several views, and in which- Figure l is a front view of the line ruling device which forms the subject matter of the present invention Fhzure 2 is a rear view thereof.

Figure 3 is a side elevation.

Figure d is a top plan view showing the device in operative position.

Figure 5 is a ar view with the or inoperative position.

Figure 6 is a detail view of and inking cylinder,

Figure 7 is a perspective view of the pivot shaft.

Figure 8 is a similar view of the cam dish.

Referring to the drawing in detail, the refer ence numeral 5 indicates the attaching plate of our type-bar guide, which includes an upright 2 having a tapered face and which is vertically or recessed as at 3 for the passage of the guide it stems on the type heads of the type bars. in applying our device to a typewriter, the type bar guide thereon is removed and our guide substituted therefor.

The upright has formed on the upper end thereof and extending forwardly therefrom a pair of guide members ti and 5 extending from opposite sides of the recess as best shown in Figure 5, and the guide member 5 is. in the form of a bracket, in that it is provided with an enlarged fiat outer end 6 to act as an attaching and supporting means for parts which will be presently described.

The enlarged guide member or bracket 5 has a curved front edge and a square cornered opening therethrough adjacent its outer end, for the purpose of receiving the square cornered portion 3 or" a shaft ll, whereby the shaft will be held fixed device in idle 23 the wheel carrying and against rotation with respect to the bracket The shaft 5 has formed thereon just above the square cornered portion, an enlarged rounded por= tion it that has pivotally mounted thereon, an arm l i that extends laterally from the lower end of a body member i2 and extending from the body member inopposed relation with respect to the aim ii is a handle 413, the latter having a ser== rated outer end or linger gripping portion The body member 82 has formed thereon superimposed aperturcd lugs iii to receive a screw bolt it mounted for rotation therein and threaded on the screw bolt iii are lugs ill which extend from a cylinder it, consequently, it will be seen that the cylinder is carried by the handled body memher to be moved therewith, and the cylinder is capable of vertical movement through the instru mentality oi the screw bolt l8 and for a p rp se which will be later apparent.

Formed on the cylinder are ears I! arranged in cooperating-pairs and the pairs are superimposed as well as disposed, at right angles with respect to each other, as best shown in Figure 3. Journaled between the ears of each pair is a line drawing wheel -20, and by disposing the pairs of ears at right angles with respect to eachother, it will be seen that the wheels are arranged accordingly. The wheels extend into the cylinder which has an inking wick 2| therein, and the cylinder has an open upper end which is closed by a pivoted cover plate 22.

Depending from the cylinder is a guide stud 23 mounted for disposal between the guide members and to ride along the curved forward edge of the guide member or bracket 5, as will be apparent upon inspection of Figures 1 and 5. The

guide stem is held accordingly through the instrumentality of a coil spring '24 having its end convolutions extended outwardly to contact the cylinder and the handle l3.

From the foregoing, it will be seen that the cylinder carries the wheels for movement to an operative position, as shown in Figure 4 or to an idle or inoperative position of Figure 5 by movement of the handle I3, and inorder to hold the wheels in either of these positions, against casual movement, we employ a spring pressed cam 'means which includes a collar 25 having a square cornered opening therethrough to fit the square cornered portion 26 of the shaft 8, and the shaft has formed thereon a disk 21 provided with diametrically opposed recesses 28 for the passage of cam members 29 therethrough for disposal in depressions 30 arranged in the enlarged outer end of the arm I I, the cam members being formed on and depending from the collar 25, and having triangular shaped lower end portions to fit within the depressions which are shaped accordingly for that purpose. 1

The shaft terminates at its upper end into a threaded portion to receive a nut 3i and mounted on the collar 25 is a washer 32 which acts as an abutment means for the lower convolution of a coil spring 33 that has its upper convolution engaging the nut 3l', whereby the pressure of the spring 33 can be regulated as will be apparent.

In view of the fact that the shaft 8 and collar 25 are held against rotation, and the arm II is mounted for rotation on the shaft, it will be obvious that the cam members ride into and out of the depressions 30, and are received therein when the wheels are in operative position as shown in Figure 4, consequently pressure will be exerted against Y the wheels, and this pressure is increased in accordance with thenumber and thickness of sheets within the typewriter, wherefore our line ruling device is not only capable of drawing horizontal and vertical lines on asingle sheet but also can impress lines on a maximum number of carbon sheets.

In order to draw a horizontal line by our device, the wheels are disposed to theposition as shown in Figure 4 and the carriage of the typewriter is then moved longitudinally in either direction. However when it is desired to draw versheet or sheets against the vertical wheel so that the vertical wheel can act'thereon for drawing its lines accordingly.

It is thought from the foregoing description that the advantages and novel features of our invention will be readily apparent.

We desire it to be understood that we may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims We claim:
